ments in Printing-Telegraphs, of which thev following is a specification'.

1o Our invention relates to that kind of apparatus in which letters or characters are printed type by type from a type wheel or platen which is set to different positions for printing different characters by means of a series A I of' magnets, different ones of whichrsingly or in different combinations operate upon typewheel-adjusting mechanisms, according to the particular character to be printed. f

Our invention relates mainly to the adjust- 2o ing mechanisms, and is designed to provide a simple and effective device positive and oertain in action and free from lost motion for giving the desired adjusted movements to the type wheel or platen under the single or combined action of two or more magnets.

The invention is applicableeither to giving the type wheel or platen a movement of translation axially or longitudinally, as is done where two or more rings or lines of type 3o are employed, or to giving it a movement of rotation or transversely in one or both directions, or to giving it both movements.

`We have herein described andfshown the invention as applied to a type-wheel which is given both movements, the axial movement to bring any particular ring or line of type to position for printing being given by one mechanism andthe movement of rotation to bring a particular type of a ring or line to position 4o for printing being given by another mechanism, both mechanisms, however, embodying our invention.

Preferably the several adjuster-magnets are operated in the circuits of a sun flower or distributer, after the manner described in patent of Charles L. Buckingham, No. 487,982, or are otherwise controlled in their operation over asingle line by a multiple or harmonic system of transmission, as described in other 5o patents to the same party. VWe do not, however, limit ourselves to any particular means for energizing different magnets singly or in the different desired combinations.

- Another feature of our invention relates to i the manner of controlling the operation of a restoring-circuit used in connection with selecting-relays, which being placed in different branches of a sunflower or distributer, as in Patent No. 487,982, before referred to, require to be restored to normal position after 6o the completion of each cycle of changes produced by the distributer. The object of this part of the invention is to properly adjust the restoring or resetting operation to the action of a dogging-magnet which holds the type- 65. wheel in the' position to which it has been adjusted, as well as to properly determine or adjust the related times of action of other devices, such as the press-pad, paper-feed, dac.

The principle of the rst part of our inven- 7o tion consists in the combination, with the type wheel or platen, of an arm or lever both ends of which are movable singly or together under the action of two impellingdevices connected, respectively,to the ends of said lever, each end being movable around the other as a fulcrum, while the said arm or lever is itself connected to the type-wheel by proper mechanism for moving it axially or rotating it', as may be desired. By moving one end 8a ofthe lever about onefulcrum the wheel may be moved axially a certain distance. By moving the opposite end about the other as a fulcrum the wheel may be moved axially another certain required distance, preferably different in extent from the first. If the extent of movement be made greater in one case than in the other thel simultaneous movement of both ends each at the same time about the other as a fulcrum will cause the point of at- 9o tachment to the type-wheel axis to move to an intermediate extent or position which is the resultant of the combined movements,or a distance equal to the sum of the individual movements. For convenience the lever or arrangements of thelever hereinafter described may be termed a whifiietree arrangement. The second part ofourinvention consists in combinations of local circuits,.relays, and distributer or sunfiower branches, as more .parico ticularly hereinafter described andv claimed. In the accompanying drawings, Figure l is a general side elevation of an apparatus embodying the means for adjusting the typewheel. Fig. 2 is a general perspective view of the type-wheeladjusting apparatus, and shows one of the adjuster-magnets connected to the system oflevers which produce rotation of the wheel. Fig. 3 is a detailsection through the means for connecting the lever which moves the type-wheel axially. Fig. 4 is a perspective illustrating a modification and means for producing rotation of the wheel through the combined operation of a series of levers. Fig. 5 illustrates in plan a modification in the system of levers where it is desired to provide for three different adjusted movements by the action of adjusters acting singly. Figs. Gand 7 indicate other modifications to be hereinafter described. Fig. S is a general diagram of the circuits and apparatus, and shows that part of our invention which relates to the manner of controlling the operation of the restoring-circuitand thedoggingfmagnet. Fig. 9 shows in perspectivea modification wherein a direct connection is made between the arm or lever and the type-wheel shaft by means of a crank. Figs. l0 and 1l illustrate the invention extended to include four or five different adjusters or actuating-levers, giving singly independent movements of valves represented by the terms of a geometrical series and in various combinations giving other movements whereby the wheelor platen may be made to assume any one of a larger num ber of positions by movements to and fro in the same line. Fig. l2 illustrates a further modification, wherein the rocking or transverse movement of the wheel or platen is made less and the longitudinal movement correspondingly greater than in Fig. 9.

IV indicates a type-wheel having its types divided into four rings, and adjustable circumferentially and axially to the different positions required for printing the characters by means of the various impelling devices brought into operation successively or simultaneously in propercombination, as described in Patents Nos. 487,981 and 487,982.

The particular devices for supporting the paper not being essential to the invention herein described are not more fully set forth. It is sufficient to say that the paper may be in the form of a tube fed around a cylinder P, Fig. I, by any suitable feed mechanism, and having its fresh surfaces for printing brought into position beneath the type and between the wheel and an opening in the cylinder P, the latter containing a suitable presspad p.

The type-wheel is mounted in suitable bearings, as indicated in Fig. 1, to permitit to be moved axially and circumferentially. At one end it is connected to a lever42, which adjusts it axially, as shown in Fig. 2, the connection being such as not to interfere with the free rotation, while at the other end it is connected by a pin 25 with a sleeve or cylinder c, constituting a follower, which is rotated by the action of a driving device, as hereinafter described, and having a straight slot in which the pin 25 works, so that while the sleeve c4 may be rotated by the mechanism to be described, and the wheel also thereby rotated, there will be at this point of connection no interference with the longitudinal or axial movement of the type-wheel.

F G I-I I .I are adjuster levers or arms, operated by connection with the armatures 12 of corresponding adjuster-magnets or pairs of magnets CL4 b4. These armatures operate upon systems of levers for the purpose'of rotating the wheel and moving it axially, the arm or combination of arms which produces the adjusted movement being determined by the operation ofthe sunflower and a series of selecting-relays controlled from the contacts of the sunflower and governing, at their front and back stops, respectively, the circuits of magnets b4 a, each relay controlling one pair of said magnets. The impelling-armsl J, Fig. 2, operate upon the lever 42, which serves to adjust the type-wheel axially to position for printing from different rings of type. By preference we cause one impelling device to move the wheelin one direction and the other to move it in the opposite direction, since by this means We limit the extent of the movement which it is necessary to give in order to secure the three adjusted positions of the type-wheel axially. Preferably we connect the type-wheel axis to the center of the lever and secure different extents of movement accompanying the action of the impelling devices singly by moving the impelling devices themselves different distances; but it would obviously be within our invention to connect the type-wheel lo one side of the center of the lever, or to some part thereof such that the impelling devices at their point of attachment to the bar should have different mechanical advantages, so that the same extent of movement of the opposite ends thereof would produce different extents of movement at the point of attachment of the type-wheel axis.

In the drawings, Figs. 2 and 4, we have shown the arrangement wherein the typewheel is connected to the center of the lever 42. The two fulerums of said lever are indicated at 43 44, and are formed by the pivotal connection of the links 45 4G therewith. Through the latter links the adjusting or iinpelling devices I J operate upon the lever 42, I being connected to a lever 47, to which 46 is joined, and .I to a lever 48, to which 45 is joined. The type-wheel axis is connected to 42 bya short rod or piece 51, which is pinned at one end to the lever 42 and at the other connected to the shaft or axis in such a way as not to interfere with the free rotation thereof, while at the same time being adapted to move it positively backward and forward. For this purpose the piece 5l is turned down so that it may pass through the end of a bushing tapped into the hollow end of the ICO IZO

type-wheel axis, and within .the end has a head fastened to it, as shown in Fig. 3, the whole forming a simple coupling adapted to the purpose stated. Adjuster I turns the end 43 of lever 42 about 44 as a fulcrum so as to move the shaft the space of one ring of type in the direction of the arrow 50. AdjusterJ moves the end 44 of lever 42 Iabout 43 as a fulcrum a distance sufficient to adjust the axis in the direction of the arrow 49 two rings of type in an obvious manner. When both adj usters' operate, the end 44 moves about 43as a tulcrum a distance sufficient to carry the type axially two rings of type in the direction of arrow 49, but the end 43 is at the same time moved about 44 as a fulcrum so as to carry the point of attachment ot' the type-wheel shaft backward in the direction of arrow 50 axially the space of one ring, and the resultant of the action is the movement ot the type-wheel in the direction of arrow 49 one ring. As will be seen, the wheel may thus be moved from the normal position in which the second ring from the right, Fig. 1, is in position to print into position to bring either of the three other rings into position over the pad. As both adjuster-levers are shown as having operated, the second ring of type from the left, Fig. 1, is in position to print. If the ring at the extreme right or left were normally in position it would obl viously be necessary to give the wheel an extreme axial movement over three rings, and the movementof both ends of the lever 42, Fig. 2, acting singly would in that case have to bein the same direction, whereas in the arrangement shown the two ends move in opposite directions, and the greatest extent of movement required is over the space o i two rings. It will be obvious that the type-wheel axis might be attached at one side of the center between the fulcrums 43 44, as indicated in Fig. 6,in which case the same extentof movement of the ends43 44, under the action of the impelling devices, could be employed to secure the three different adjustedpositions, the movements ot 5l from the normal position being either all in the same direction from normal or in opposite directions, aceording to the movement given to the ends 43 44 by the impelling devices andas may be required by the normal position of the press with respectto the wheel-that is to say, whether under one of the inner rings ot type or one of the outer rings. Instead of connecting 51 between the fulcrums it might be connected outside the same, as indicated in Fig. 7, the same principle of operation existing in this case, however, as in the others, the movement in any case depending upon the well-known principles governing the relative positions of power, work, and fulcrum in le- We do not limit ourselves to the applicaplicable to one with three rings or rows requiring but two changes of position of the wheel axially. In this case a simultaneous or combined action of the adjustermagnets would not be required.

The forward or setting motion of each arm is produced by an electromagnet a4 and its backward or resetting movement by the electromagnet b4, the latter taking the place of the retracting-spring by acting on the arma-` vpeiling-lever 42 may obviously begreatly varied without departing from our. invention, the essential feature of which consists in making the lever 42 movable around either or both of two fulcrums, as before described, under the action of the impelling devices.

The rotation of the type-wheel may be effected by the employment of a lever 42 at the opposite end of the shaft impelled by le- Vers F Gin a similar manner. As the type.- wheel has, however, eight characters on its periphery we combine therewith another adjuster-lever H and intermediate lever 42 similar to 42 for obtaining by a combination of actions the requisite different adjusted positions. Adjusters F and G operate upon lever 42 in a similar manner to adjusters I J. Adjuster F is connected, as shown, by a link with a lever 49, and the latter by a link with one pivotal end of lever 42. Adjuster G is connected through attachment to lever 42 with the other end of lever 42 by means of a .link 3l, as shown. For the purpose, of combining the action of adjuster H with that of adjusters F G, the pivotal point of 42 is that where the lever-adjuster G is attached and adjuster H is connected with lever 42"' through a lever 50 and connecting-link, as clearly shown. By these means it will be obvious that the action of levers Gand ll upon the link 3l, and through the latter upon the type-wheel, will be combined in much the same way as that of the two adjusters indicated in Fig. 7.

The connection of the lever 42 with the type-wheel for rotating it may be made by a rod or driver w3, carrying a pin 24, which By this means the reciprocation of the from its position of rest, and adjuster G, by moving under the action of its magnet 0.4 in the direction of the arrow, serves to move the type-wheel in the opposite direction one-quarter of a revolution by moving the lever 42' in an opposite direction to the direction in which F moves it. When G operates, the lever 42 turns on the fulcrum at the point where it is connected with the adjuster H. The latter serves to move the type-wheel through the connected system of links and levers oneeighth of a revolution in the same direction in which the lever G moves it.

As will be obvious, if G and H operate at the same time they will move the wheel threeeighths of a revolution or three spaces; or if at the same time that F operates G should operate, then the wheel would be set onequarter of a revolution instead of one-half the revolution in the direction in which F moves it. By a combination of movements of the levers, or by operating them separately, it is obvious that the wheel may be turned to either one of seven positions from the normal position, which is the eighth position.

Fig. 5 illustrates a modification in the manner of combining the action of three adjusters with the type wheel or platen through the combined action of two levers 42' 42", the said adjusters being connected at the points indicated by the letters F G H. The rod or bar w3, which is herein termed the di-ivel, may be connected with the type-wheel to rotate it by means of a rack and pinion H', as indicated in Fig. 4, instead of by means of the pin and spiral slot. lAnother means that may be used for connecting the driver-bar w3 with the type-platen when the latter is mounted to have a movement of rotation is shown in Fig. 9. Here the bar is connected by a crank with the sleeve c4, which is properly mounted to be capable of rotation, but not of longitudinal movement. The typewheel shaft slides axially in the sleeve, but is connected therewith by a pin and straight slot, as before described, so that while the wheel may be rotated by the crank it may also be moved longitudinally or axially by other devices without interference from the connection with the sleeve. As the crankconnection will not give exactly equal movements of rotation for all linear movements of the bar, it is obviously desirable to space the characters in each circumferential row on the platen accordinglythat is to say, to place those at the extremes of the arc of vibration nearer together than those at the center, where the linear movement of the bar will give the greatest throw to the crank. In this ligure the type-wheel is modified with reference to the use of the crank so as to constitute an arc of a cylinder instead of a wheel or complete cylinder, and the dogging-cylinder hereinafter described is correspondingly modified.

Owing to the difference in the throw of the crank, as just mentioned, we prefer, when using the same, to modify the apparatus as indicated in Fig. l2 so that the crank will be required to place the type-platen in four different positions only. As clearly shown in this figure, the platen or wheel segment has eight rows of type and four type only in each row. By a combination of three adjusters the platen or segment may be shifted longitudinally or axially to position for printing from any row, while two adj usters operating in combination upon the crank selects the position for printing from any type of a row by giving the transverse or circumferential movement to the platen.

Obviously our invention admits of extension to three forms or any greater number of levers, each adapted to move around either or both of two fulcrums under the action of the adjuster-levers, the independent movements given by the several adjusters being respectively of values represented by the terms of a geometrical series. Each lever which has the capacity of moving around either or both of its two fulcrums may obviously do so under the action of the two adjusters immediately connected to it, or in response to the resultant action or actions of several of the adjuster-levers, the movement of the levers immediately connected then operating wit-h a resultant movement communicated from the others.

In Fig. lO we show an arrangement of three double fulcrum-levers 42 42' 42" and four adjusters F G H H', similar to that shown in Fig. 2, but with an added adjuster-lever H', which is adapted to give an independent movement different` from the others, but serves to modify the action of H when operated at the same time by acting upon the double fulcrum-lever 42", to which H is connected instead of to a lever, as 50 in Fig. 2.

Fig. 11 shows four double fulcrum-levers 42 42'42"42'and five adjusters F G H H' H, coupled together in a manner somewhat resembling Fig. 5. Lever 42' is subjected to the action of adjustersv G H, coupled to one end of 42', and H' H", coupled to the other end, so that either G or H, operating alone or in conjunction with either H' or H", will act on the type-wheel by means of the double fulcrum-lever 42', as before explained. In order that the adjusters G and H may impart each its proper movement to 42', acting singly or in combination, and give the desired resultant movement, they are coupled to the double fulcrum-lever 42", and by connection of the latter with 42' by a link communicate movement to the latter. H' and H" operate in a similar way upon the double fulcrumlever 42", coupled to the opposite end of 42.

A further extension of the principle to eight adjusters in place of the four G H H' H", could obviously be made by coupling a pair of adjusters to each end of 42" and 42"',

in the same way that a pair is connected to each end of 42'.

In connection with the type-wheel an auto- IOD XID

matic (logging or locking device which shall come into action as soon as the wheel is adjusted to position for printing any letter, and positively lock or hold it in such position during the impression, as well as prevent it from being thrown out of such position in the adjusting operation, is employed. This dogging device may be controlled over a circuit governed by the sunflower or distributer or by any other portion of the mechanism whose action is timed to bring the dog into position just at 'the instant the type-wheel reaches the adjusted position for the character. The particular mechanical construction of the dog may bevery greatly varied.

The dogging-magnet is indicated at 90, Figs. 1, 8, and 9 Its circuit is closed toward the end of the cycle of changes in which the adjuster-magnets are required to set the type-wheel to position for printing any particular letter. The electromagnet 90 has an armature consisting of a rock portion 96, pivoted in the frame above it, and having at the opposite ends of the magnet the arms 97, adapted to move to and from the poles of said magnet in a line transverse to the axis of the magnets core. Practically the same construction is used for the armatures 12'of the electromagnets a4 b4. A form ot' dog which we may employ consistsof a pin v92, upon the head of which bears an arm 91, projecting from they shaft 96 of the electomagnet 90, while a spring 73, surrounding the pin,op erates to hold the pin raised as well as to retract the armature-lever. (See Fig. 8.)

Mounted preferably on the same shaft with I the typewheel, so as to rotate and move axially with the wheel, is a suitable dogging-cylinder having depressions or seats adapted to co-operate with the clogging-,pin for locking the wheel in each of its adjusted positions. At 95, Fig. 1, is shown such a cylinder. The point of the dog or pin is adapted lto enter the holes or depressions in said cylinder 95,-

which forms a portion ofthe type-wheel shaft, and has dogging-points or depressions corresponding in number and position of the char-- acters on the type-wheel, so that when the type-wheel is in position to print any character one of the seats or holes will be beneath 'the point of the dogging-pin. the pin normally just clears the surface of the cylinder in which the holes are formed. The point of the pin is conical in form, so .that when the dog is forced downward it may iind the hole and will operate to adjust the wheel to precise position for printing should it be slightly out of position when the dog is operated.

In the operation of the type-wheel the cylinder 95 moves freely under the point of the dog, but on the instant the adjuster devices complete their action upon the type-wheel the (logging-magnet is energized and the point of the dog is thereby forced down' with the result already stated. This magnet may be tributer.

The point otV controlled as indicated in the diagram, and as will be described further on. A

Having described the general principles of the adjusting mechanism for setting the typewheel and the form of dogging-magnet that may be employed in connection therewith, we will proceed to describe a way in which theyV may be operated by means ot' a sunflower or distributer and arrangement of circuits resembling that described in our previous application, tiled April 27, `1894:, Serial No. 534,480, and in so doing will describe that other portion of our invention which relates to the manner of adjusting the resetting, the dogging, and the printing operations to one another.

R, Fig. 8, is a polarized main-line relay whose armature vibrates under the action of the alternating pulses sent by the transmitter and thereby closes in rapid alternation the branches 10 l0 of a circuit 10, leading'from a battery or other generator L B. These branches contain, respectively, coils of alocal relay S, whose armature remains unaffected so long as the pulses are short, but becomes affected on the prolongation'of any pulse, thereby causing the relay to prolong for an instant. The closure of either branch causes a'sufficient excitation of the magnet to drawup the armature and thereby close a circuit 12,' branched through the contacts ot the sun- -flower or distributer and the several selecting-relays U V'W X Y, connected to said dis- The two branches 10 10of the circuit lO include also coils of an escapementmagnet O, whose armature is vibrated by the action `ot' the currents in the branches operating alternately, and is thereby made to work the anchor-escapement a of the distributer. 2 is the power-driven escapement-wheel of said distributer carrying aseries of actuatingpins, which operate upon circuit-closers composed of pivoted arms 18, six in number, carryingcontact-springs d, which by the operation ofthe actuating-pins are moved in to contact with stops f. Normally the springs are held out of contact with said stops by retractor-springs 21. Five of the circuit-closers control, respectively,the branches containing the selecting-relays U V W XYand are operated by the pins, so as to close and open said branches successively. The sixth circuitcloser governs a circuit indicated by the dotted line 15, whereby a type-wheel press-pad is operated, the selector-relays are restored to normal position, and the dogging-magnet is energized. The six circuit-closers are actuated in succession in' a movement ofthe wheel 2 a space corresponding to that between two actuating-pins, and such movement of the wheel is accomplished in six half-vibrations of the anchor-escapement corresponding to six alternations of the main-line current in relay R.

-In the operation of the circuit-closers successive pins of Wheel 2 operate upon success- IOO ive arms 18 to produce one complete cycle of changes, this action resulting from the spacing of the pins so as to be less than the space between two arms by an amount equal approximately to one-sixth of the whole arc covered by the latter, so that the cycle of circuit changes is produced once for each movement of the wheel over the space covered by two pins. Each cycle closes with the operation of the arm 18', which controls the press-magnet and the restoring-circuit. The tive other arms are connected in regular order to the relays controlling the magnets which operate the type-wheel adjusters; but that magnet which has the most work to do, or whose adjusting mechanism has to move the farthest in adjusting the type-wheel, has its relay connected to the stop of the circuit-closerl which is rst operated in the cycle of changes produced by the distributer and so in regular succession. That one of the magnets which having the least to do will require the least time has its relay connected, therefore, to the arm which is the fth in operation in the cycle, those magnets which have more to do being brought. into circuit ahead of it. By this arrangement the action of the adjusters is insured before the restoring devices come into action.

The several selecting-relays are in branches of the circuit 12, which is normally broken at the contact of local relay S, as shown, said circuit being carried through the distributerarms by connection to the plate 20, in which said arms are pivoted, or in any other suitable way. As each branch is closed once in each cycle, any of said relays-one or all-may be operated in such cycle if the pulse which causes the distributer to close the branch of a relay be prolonged so as to also operate thelocal relay S. In the absence of the prolongation no effect will be produced, although the branch is closed. Hence by properly arranging the prolongations or other modification of the main-line pulses to cause the de sired prolongation at the various points in the local cycle, said selecting-relays may be actuated singly or in any desired combination. Each relay operated closes the local circuit 13 through its corresponding adjuster-inagnet a4, the., in obvious manner to actuate the adjusting mechanism and set the type-wheel to position for printing the desired character. The printing is done on the sixth closure of the cycle of changes produced by the distributer, and at the same time the adjuster magnet or magnets concerned in adjusting the type-wheel are thrown out of action, owing to the fact that the selecting-relays are restored to normal position by the action of a battery or generator L B', in whose circuit 99 are coils on all of said relays which restore the armature to normal position. In this positionof the armatures the local circuit 13 is through themagnets h4, tbc., of the adjustinglevers. By these magnets the levers are held in normal position, and those which have been active in any cycle are restored to normal position by a positive action. It will be readily understood that the selector-relays are so constructed or their armatures so mounted that they will retain the position in which they are placed by the closure of circuit 12 until at the end of the cycle the restoring-circuit 99 is closed. Synchronism of the sunfiower or distributer is attained by a stop l), which is normallyin position to stop the wheel at the end of each cycle by engaging with teeth on wheel 127, secured to the distributer. It is withdrawn to allow the wheel to move to position to begin a new cycle by the action of magnet S3. The latter magnet has two coils in branches respectively of the circuit through the contacts of relay R. The magnet is polarized and the coils of the branches 10 10 are reversely wound. Short pulses do not affect its armature nor do long pulses unless in the branch 10', closed on the sixth pulse of each transmission, in which branch such prolonged pulse operates to strengthen the magnetism and draw up the armaturelever bs, which carries the stop b, thereby-removing it from the path of the tooth on wheel 197, which tooth has on the fifth pulse moved up to the stop. Long pulses in the other branch oppose the polarity ot' the magnet and the armature remains retracted. From time to time a number of short pulses, greater than six, winding up with the long pulse which will close the branch by which the stop is withdrawn and the wheel allowed to rotate to position to begin a new cycle of changes, may be sent. The circuit-closer 18 for the distributer closes at the end of each cycle, by which a character is transmitted, the local circuit containing a relay 020 and the dogging-magnet 90. Relay c2() establishes the restoring-circuit 99, which sets the selectingrelay armature back to normalposition, which is followed bythe restoration of the adjusterlevers through the action of b4, &c. The delay in the action of the latter, owing to the fact that they are in a double-relayed circuit, from 15 to 99, and from the latter to 13, gives time for the operation of the press-magnet, effected as follows: The dogging-magnet holds the type-wheel in. position for printing, and its armature in actuating the (logging-pin closes at contact 8O a local circuit which includes the press-magnet c', whose armature operates the presspad and effects an impression. The armature of the press-magnetdropping back to normal position closes the local for the magnet h, which in drawing up its armature produces a momentary release of the paper-feed devices, of any desired. construction, not necessary to herein more particu larly describe.

By adjusting the contacts of relay c"10 or its retractor, or by otherwise determining its action in closing the relayed circuit 99, the action of the restoring-circuits may be timed with reference to the operation of printing, so that there shall be no movement or tendency to movement of the type-wheel until the instant after the impression is effected.

The general operation is brieiiy as follows: With each transmission of six alternating pulses over the line by a perforated tape or other form ot transmitter the connections controlled by the distributer are made in rapid succession. The prolongation of one of said pulses produces by relay S the operation of an adjuster-magnet, the circuit of whose adj Uster-relay is closed by that pulse, and thereby operates upon the type-wheel to set it to position for printing the desired character. One, two, or any number of adjusters operate according to what pulses are prolonged, each adj uster-relay and corresponding adjuster retaining the position into which it is placed by the action of the prolonged pulse. On the sixth pulse the circuit-closer 18 comes into operation, thereby clogging the type-wheelin position and effecting in immediate succession the printing followed through the chain ofactions originatingin relay 020 by the resetting or restoring of the adjusting apparatus. The paper-feed follows upon the printing.

The arrangement of local circuits herein described for controlling the operation of the press, clogging, and paper-feed magnets and the action of the restoring-circuits and restoring-magnets is, it will be obvious, useful in connection with other mechanisms for setting the type-wheel to dierent adj usted positions by the action of several adjuster-magnets, different ones of which singly or in combination are energized according' to the character to be printed. l

What we claim as our invention is- 1. The combination with the type-wheel or platen, of two adjuster magnets, and an intermediate lever having two fulcrums around either or both of which it may turn under the action of said adjuster magnetsA working singly or in combination.

said wheel positively in both directions, two or more adjuster magnets, and a lever connecting the said magnets with the head and adapted to move around either or both of two fulcrums according to the magnet or magnets operated.

4. The combination `with the type-wheel, ot' a reciprocating head or follower connected with said wheel through devices adapted to rotate the same, two or more adjuster magnets, and a lever connecting the said magnets with the head and adapted to move around either or both of two fulcrums according to the magnet or magnets operated.

5. The combination with a type-wheel, of three adjusting and two connecting levers each adapted to move around either or both of two fulcrums according to the adjuster or combination of adjusters operating.

6. The combination with the distributer, of a series of selecting relays and adjuster magnets controlled thereby, of a restoring circuit, and a controlling relay for the latter in one ot' the distributer branches.

7. The combination with the distributer, of a series'of selecting relays, a series of adjuster magnets, a restoring circuit, a type-Wheel, a dogging magnet for holding the type-Wheel in adjusted position, and a distributer branch including the dogging magnet and a relay for the restoring circuit.

8. The combination with the type-wheel or platen, of a whiflietree or system of whiftletrees, and two or more adjuster magnets, as and for the purpose described.

9. The combination with a type-wheel or platen adjustable in one direction to bring dierent rows of type into position for printing and in a direction at right angles to the rst to bring different type of a row into position, of two Whiftletree levers or system of levers connected therewith to give both said motions, and two or more adjusters or actuators acting singly or in combination as described upon each lever or system of levers.
